AIPMT PRELIMS 2002 Physics Magnetic Oscillations MCQ Question
Type: MCQ-conceptual-Hard-Class 12
Two bar magnets having same geometry with magnetic moments M and 2M, are firstly placed in such a way that their similar poles are same side then its time period of oscillation is T₁. Now the polarity of one of the magnet is reversed then time period of oscillation is T₂, then :-
A
T₁ < T₂
B
T₁ = T₂
C
T₁ > T₂
D
T₂ = ∞
Correct Answer
Option A
Detailed Explanation
Reversing the polarity increases the net magnetic moment, reducing the time period of oscillation.
